The ExPetrum Pack

Concept of ExPetrum (taken from the mod page): ExPetrum aims to make the game as realistic as possible while maintaining an enjoyable progression system. In ExPetrum you will start as a cave man scavenging for food and water. As you explore the world you will find rocks that you can use to create your first brittle yet effective stone tools. Finding ores isn’t as challenging as in similar mods as there are surface hints. Then you will use ceramics to smelt your first copper. Fast-forward a bit and you’ll be making first bronze alloys in a crucible and smithing them into tools at an anvil. Then using a bloomery you will create your first iron. With that iron you will be able to create first devices using rotary power to do work. Then you will use that rotary power to make steel in your own blast furnace. Everything is accurate and realistic. Alloy compositions. Melting temperatures. Food spoiling. Metal properties. And much more.
